Species of the genus Thoracostrongylus Bernhauer, 1915 occurring in China are reviewed. Four new species and one new subspecies are described: T. baishanzuensis sp. nov. (Zhejiang), T. bicolor sp. nov. (Guangdong, Guangxi, Hunan, Yunnan), T. brachypterus sp. nov. (Sichuan), T. chrysites sp. nov. (Fujian), and T. formosanus flavipes ssp. nov. (Zhejiang, Fujian, Hubei, Hunan, Sichuan, Guangxi, Guangdong, Anhui, Jiangxi). A new synonymy is proposed: T. baoxingensis Yang, Zhou & Schillhammer, 2011 syn. nov. is in fact T. acerosus Yang, Zhou & Schillhammer, 2011. New provincial records for T. acerosus Yang, Zhou & Schillhammer, 2011 are reported. A key to Chinese species of the genus is provided.

Thoracostrongylus Bernhauer, 1915 is a genus strictly distributed in east and southeast Asia. It was originally established as a subgenus of Ontholestes Ganglbauer, 1895, and later regarded as a separate genus (
At present, sixteen species of the genus have been described worldwide, eleven of them recorded from China: T. acerosus Yang, Zhou & Schillhammer, 2011 from Hubei and Sichuan; T. aduncatus Yang, Zhou & Schillhammer, 2011 from Yunnan; T. baoxingensis Yang, Zhou & Schillhammer, 2011 from Sichuan; T. birmanus (Fauvel, 1895) from Hainan and Yunnan; T. diaoluoensis Yang, Zhou & Schillhammer, 2011 from Hainan; T. formosanus Shibata, 1982 from Zhejiang, Fujian, Hubei, Hunan, Sichuan and Taiwan; T. fujianensis Yang, Zhou & Schillhammer, 2011 from Fujian; T. malaisei Scheerpeltz, 1965 from Yunnan; T. miyakei Bernhauer, 1943 from Sichuan and Taiwan; T. sarawakensis (Bernhauer, 1915) from Hainan; and T. velutinus Scheerpeltz, 1965 from Yunnan. Thoracostrongylus baoxingensis Yang, Zhou & Schillhammer, 2011 syn. nov. is here synonymized with T. acerosus Yang, Zhou & Schillhammer, 2011. The records of T. formosanus from mainland China, however, have turned out to be a distinct subspecies. Thus, including four new species described herein, the total number of Thoracostrongylus species is increased to 20 and the number of Chinese species is increased to 14 plus one subspecies.
The specimens examined in this paper were collected by sifting leaf litter, and by flight intercept traps and pitfall traps. They were subsequently killed with ethyl acetate. For examination of the genitalia, the last three abdominal segments were detached from the body after relaxing in hot water. The aedeagus together with other dissected pieces, were mounted in Euparal (Chroma Gesellschaft Schmidt, Koengen, Germany) on plastic slides beneath the card-mounted specimens. Photographs of sexual characters were taken with a Canon G9 camera attached to an Olympus SZX 16 stereoscope; habitus photographs were taken with a Canon macro lens MP-E 65 mm attached to a Canon EOS 7D camera and stacked with Zerene Stacker (http://www.zerenesystems.com/cms/stacker).
The specimens treated in this study are deposited in the following public and private collections:
ASC Aleš Smetana Collection, the National Museum of Nature and Science, Toshiba, Japan;
BFC Collection of Benedikt Feldmann, Münster, Germany;
MSC Michael Schülke Collection, in Museum für Naturkunde, Berlin, Germany;
SHNU Department of Biology, Shanghai Normal University, P. R. China;
VAC Volker Assing Collection, Hannover, Germany† (will be deposited in Zoologisches Museum, Berlin).
Body measurements are abbreviated as follows:
BL body length, measured from the anterior margin of the clypeus to the posterior margin of abdominal tergite X;
CL length of eye;
EL length of elytra, measured from humeral angle;
EW width of elytra at the widest point;
FL forebody length, measured from the anterior margin of the clypeus to the apex of the elytra (apicolateral angle);
HL length of head along the midline;
HW width of head including eyes;
PL length of pronotum along the midline;
PO length of post-ocular region;
PW width of pronotum at the widest point.

The subspecies is most similar to T. velutinus from Yunnan and Myanmar, but can be easily distinguished by the usually black mid and hind tibiae and tarsi. Both differ from other species from east and southeast China in the abdominal tergites III–VI without triangular mediobasal golden tomentose patch.

The new subspecies differs from the nominate subspecies in the slightly shorter tempora, and entirely reddish to yellowish antennae and legs (except a dark band on the femora), while the nominate subspecies has almost entirely dark antennae, and black tibiae and tarsi. Even in paler (teneral) specimens of the nominate subspecies, the antennae and legs are at least partly darkened.
The subspecies is widespread in China (Zhejiang, Fujian, Hubei, Hunan, Sichuan, Guangxi, Guangdong, Anhui, Jiangxi).

Thoracostrongylus malaisei
Scheerpeltz, 1965: 245;
China – Yunnan Prov. • 1♀; 100 km W Baoshan, Gaoligongshan Nat. Res.; 14–21 June 1993; E. Jendek & O. Sausa leg.;
China (Yunnan), Myanmar.
The species was originally described from Myanmar, and was recorded from China by Yang, Zhou & Schillhammer in 2011 based on the one female mentioned above. However, there were some inconsistencies concerning morphometrics in that paper: The character used in the key “ratio of eye longitudinal diameter to temple length < 3”, applies only to the male. However, the measurements of female T. malaisei in the same paper were written as “CL: 0.98; PO: 0.28”, and the ratio of CL/PO should be 3.5 by calculation, which conflicts with the key. Thoracostrongylus malaisei is most closely related to T. brachypterus sp. nov.; for diagnosis of these two species, see under the latter.

The species can be easily distinguished from other species from southwest China by the abdominal tergites III–VI without a triangular, mediobasal, golden tomentose patch. In general appearance, T. velutinus is most similar to T. formosanus, but may be distinguished from the nominate ssp. of the latter by its smaller body size and paler mid and hind legs, and from T. formosanus flavipes by the dark antennae.

The new species is similar to T. baishanzuensis sp. nov., but it can be easily recognized from latter by the bicolored femora. From other species of east and southeast China, it can be easily recognized by the bicolored abdomen.
The new species is similar to T. baishanzuensis sp. nov. in most aspects except for the following characters: abdominal tergites III–VII each with a longer and more distinct triangular, mediobasal, golden tomentose patch; femora each with median dark mark and apical dark mark, although the apical dark markings of the forelegs are less distinct.

The new species is the only brachypterous species of the genus so far that is known from mainland China, except for a potential record of a brachypterous T. malaisei, from which it can be separated as indicated above. The T. malaisei specimens from the type locality have rather short elytra and developed hindwings, which may be functional or not since the palisade fringe on tergite VII is very narrow. Thoracostrongylus miyakei from Taiwan also has weakly developed, non-functional hind wings and no palisade fringe on tergite VII, which differs from the new species by pronotum without impunctate midline.
The new species is almost identical to T. malaisei, from which it differs, in addition to the different aedeagus, by the differently colored labrum, which is reddish with each lobe with a large, dark brown, central spot (in T. malaisei with a black medial margin along medial excision). Most specimens of T. malaisei have at least a very narrow palisade fringe on tergite VII, which is lacking only in the single specimen from Yunnan.

The new species can be easily recognized by the reddish yellow femora and abdominal tergite VII fully covered with golden pubescence.
The new species is similar to T. baishanzuensis sp. nov. except for the following characters: pronotum reddish along posterior margin, elytra reddish at base, abdominal segments with posterior margin reddish, legs reddish yellow without dark markings, although indistinct dark markings may be present near base of profemora; abdominal tergite VI with larger median golden tomentose patch, reaching posterior margin of tergite, pair of dark tomentose spots very small; abdominal tergite VII completely covered with golden pubescence.
